BACKGROUND OF THE INVENTION

1. Field of the Invention

The field of invention relates to protective shields, and more particularly pertains to a new and improved viewing screen protective shield wherein the same may be readily secured and replaced as necessary in association with a viewing screen typically exposed to erosion.

2. Description of the Prior Art

The use of protective shields of various types to afford a level of protection to an associated device is known in the prior art. Shields of the prior art have typically been of cumbersome and expansive construction or of configurations not particularly well suited for providing replacement shields to viewing screens exposed to erosion in their environment such as fish finders and the like, and subject to solar, airborne dust particles, and water spray exposure. Examples of prior art protective shields available may be found in U.S. Pat. No. 3,995,674 to Crawford for example. The Crawford patent utilizes an angulated shield securable to an upper surface of a television receiver to deflect articles falling thereon. The angulation of the upper shield prevents objects from entering the electrical circuitry and air ducts rearwardly of the television set.

U.S. Pat. No. 4,259,568 to Dynesen sets forth a casing pivotally mounted rearwardly of a calculator that may optionally support or protect the calculator face. The Dynesen patent is of relatively rigid construction to address the problem of protecting a calculator during storage thereof.

U.S. Pat. No. 4,726,406 to Weatherspoon sets forth a flexible vinyl protective covering for securement overlying a vehicular windshield including a plurality of fasteners for securement of the shield to the automobile as well as utilizing stiffening elements along peripheral side edges of the shield to maintain the geometric integrity of the shield during use.

U.S. Pat. No. 4,733,776 to Ward sets forth a transparent shield utilizing hook and loop fasteners for securement of the shield and an associated foam protective layer to cover the elongate surfaces of various electrical devices to enable utilization of the device while simultaneously protecting the device subject to breakage during use.

U.S. Pat. No. 4,746,043 to Booker sets forth an enclosure for calculator type devices utilizing an enclosure with a transparent window positioned therethrough to enable access to the various components of the calculator or the like while simultaneously protecting the calculator from impact during use.

As such, it may be appreciated that there is a continuing need for a new and improved viewing screen protective shield wherein the same addresses both the problems of effectiveness in use and ease of installation or removal, and in this respect, the present invention substantially fulfills this need.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIGS. 1 to 3 thereof, a new and improved viewing screen protective shield embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

More specifically, it will be noted that the viewing screen protective shield 10 essentially comprises a polymetric transparent film 11 adherably securable to the viewing screen 13 of an electronic instrument 12, such as a fish finder and the like. Instruments of this class are typically exposed to adverse environmental conditions such as airborne debris, dust, water vapor, and solar exposure. The viewing screen 13 is formed with arcuate corners conventional in the industry and is of a generally convex outwardly extending geometric configuration. The film 11 may be formed to be polarized to reduce glare during usage of the device 12 and film 11 in outdoor environments.

The film 11 is formed with convex peripheral edges including top edge 14, bottom edge 15, right edge 16, and left edge 17, whereupon application of the film to the viewing screen 12, the film 11 will overlie the entire surface of the screen. A tab 18 extends diagonally outwardly of the intersection of the left and top edges 17 and 14 respectively to enhance manual grasping of the film to enable an individual to readily remove and replace the film 11 as it, rather than the more expensive screen 12, loses clarity due to exposure in particular environmental scenarios.

The intersection of the top and right edges 14 and 16, right and bottom 16 and 15, and bottom and left edges 15 and 17, are formed as arcuate corners to conform the film 11 to the viewing screen 13.

Further, natural adhesion between the polymeric film 11 and the polymeric viewing screen 13 enables adhesion of the film to the screen. Additional transparent adhesive strips 19 and 20 positioned adjacent right and left edges 16 and 17 respectively enables enhanced securement of the film 11 to the screen 13 wherein each adhesive strip is provided with a removable covering strip 22 that may be peeled away to expose the adhesive thereunder and enable the securement of the film to the screen 13. Further, it should be noted that the film 11 is of a constant thickness throughout to avoid distortion in the viewing of subject matter presented by the electronic device 12 through the viewing screen 13.

As to the manner of usage and operation of the instant invention, the same should be apparent from the above description, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
